| Summary: | Diamond is an attractive electrode material to replace mercury, which has been the material of choice for the electrochemical analysis of heavy metals in solution using stripping voltammetry. As a solid electrode however, interactions between different metal analytes can occur at diamond, which are not observed at Hg electrodes. We therefore examine the associated effects arising in the analysis of two types of mixed metal ion solutions, Cu-Cd and Cu-Zn, using stripping voltammetry at diamond electrodes. The detection of Cu is shown not to be strongly affected by the presence of either of the other metals, but the presence of Cu blocks the signal which otherwise would be detected for the second metal, Cd or Zn. © 2005 WILEY-VCH Verlag GmbH and Co.
